To all 'whom t may concer/n:

Be it known that I, ANTON MILL, a citizen of the United States, residingat Cincinnati, in the county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in Fluid-Motors, of whichthe following is a specification.

My invention relates to an improvement in iuid motors and moreparticularly to a water motor of the reciprocatory type, adapted to beactuated by ordinary water pressure and suitable for driving lightmachinery, such as a Washing machine, or, other similar devicesemploying reciprocal motion.

The object of the invention is to provide a motor of this class,employing an oscillating type of piston, in which the parts will be fewand simple, of cheap construction and of convenient and eiicientoperation.

The features of the invention are more fully set forth in thedescription of the accompanying drawings, forming a part of thisspecification, in which Figure l is a front elevation of my improved uidmotor. Fig. `2 is a section on line w, Fig. 1. Fig. 3 is a section online o, o, Fig. 1. Fig. 4 is a detailed top plan View of a base plate,illustrating the exhaust ports. Fig. 5 is an enlarged detailed sideelevation of valve with cylinder shown in section. Fig. 6 is an enlargeddetailed side elevation of the oscillating piston, with piston casingshown in section.

Preferably, the motor consists of a flat base plate 1, upon which isbolted a cylinder 2 of a type suitable to a rotary or oscillatingengine.

l3 represents a work shaft upon which is fixed a sleeve 4, having ablade 5, constituting the oscillating piston.

6 represents a stationary member containing the inlet chamber 7, and theexhaust chambers 8, 9, upon each side thereof.

10 represents a supply inlet for chamber 7, admitting water to themotor. This stationary member forms a segmental portion of the cylinder,there being an annular space between its inner end and the sleeve 4, inwhich slides the valve 12.

Chambers 8, 9, have outlet ports 14, 15, re-

spectively, and chamber 7 has inlet port 16, these ports open radiallytoward the center.

The valve is divided into two compartments 17, 18, each of which is openat its outer end to communicate freely with the interior of thecylinder, and these compartments are provided with ports 19, 20,respectively, which communicate alternately with ports 14, 16, and 15,16, as the valve is shifted. The chambers 8, 9, are provided with outletports 21, 22, communicating with the common exhaust passage 23,preferably formed in the base 1, to conduct the water from the motor.The ends of the lvalve are preferably provided with springs 24,extending outwardly toward the periphery of the cylinder and bentforwardly in position to be engaged by the oscillating piston. Thepiston consisting preferably of a plate 5, attached to the sleeve 4, andhaving the plates 25 bolted upon opposite sides thereof. The plates 25have projections 26, 26a, adapted to strike the springs 24 and valverespectively for shifting the valve.

27 represents piston packings.

In operation, the water is admitted into the chamber 7 and flows throughport 16, into the valve chamber 17, flowing out through the outer endand moving the piston to the right of the position shown in Fig. 3, thewater upon the other side of this piston flowing through the open end ofvalve lcompartment 18, through ports 20, 15, into the chamber 9 andthence out of the motor.

As the piston completes its movement to the right, the projection 26awill strike the spring 24, compressing it, until the projection 26contacts the valve, shifting the valve so as to change the ports fromoneAV position toward the other after which the spring will complete thefinal movement of the valve, so that the ports 19, 20, cover the ports14, 16, respectively, reversing the water pressure on the piston formoving the same in its opposite direction.

Having described my invention, I claim In a fluid motor, a cylinder andconcentric work shaft, a stationary segmental member comprising inletand outlet chambers and ports located at the outer periphery of thecylinder, a slide-valve controlling said ports located between the Workshaft and the inmovement to reverse the How of the Huid,
